Parra has been on the disabled list for a week with a strained left elbow and it's unclear how long he'll be sidelined. "He still has a little bit of soreness in the back of his elbow, which is a little bit more like a bone bruise. It's providing some discomfort," Reds manager Bryan Price said.

Adock, who was placed on the disabled list Thursday, suffered a full tear of the ulnar collateral ligament in his elbow. He'll likely be out until the second half of 2016. The 27-year-old had allowed 12 earned runs in 18 innings (13 relief appearances) this season for the Reds.

It was the first time he's thrown since undergoing surgery in May to repair a torn anterior capsule. "He looked normal, not like a guy coming off shoulder surgery. Pretty remarkable," Reds manager Bryan Price said. Despite Price's optimism, Marshall's appeal in free agency this winter figures to be limited give that he's coming off of a pair of shoulder operations.
